Topps has a new Opening Day tradition on its hands—and it’s all packed into the 2025 Series 1 Celebration Mega Box. Think of it as a deluxe remix of the flagship release, built on the same 350-card foundation but loaded with exclusive content you won’t find in a standard pack.

This isn’t a reboot of Opening Day in name, but the spirit is unmistakable. Timed to drop with the start of the MLB season, the Celebration Mega Box blends nostalgia, modern flair, and a healthy dose of mascot chaos to deliver something unique for collectors of all stripes.

Familiar Base, New Energy

Each box comes with 16 packs of 14 cards, sticking close to the Series 1 formula. You’ll pull base cards, inserts, and maybe an autograph or memorabilia card if the card gods are smiling. But where things get interesting is the lineup of box-only exclusives.

The headliner? Confetti parallels—color-splashed versions of base cards that show up once every three Celebration packs. That averages out to five per box, giving collectors an easy way to spot something special mid-rip.

Mascots Take Center Stage

Mascots, a staple of the former Opening Day product, make their way into flagship territory with a 25-card insert set. It’s a lighthearted nod to the ballpark experience, but Topps didn’t stop there. Ultra-rare Dynasty Mascot Autograph Patch cards also debut—combining team mascots with on-card autographs and premium patches. They’re long shots, but they’re also unlike anything else Topps is offering right now.

Insert Sets Built for Impact

Celebration Mega Boxes are loaded with vivid, stylized insert sets that add personality and pop to every rip. Standouts include:

  • 8-Bit Ballers – Pixelated flair meets superstar power.
  • Gameday Drip – Showcasing today’s players in full fashion-forward fits.
  • Power Players – A callback to early 2000s Topps designs with a fresh spin.
  • Big Head Variations – Cartoon-style exaggerations that walk the line between collectible and collectible art.
  • Walk This Way – Short prints that offer a behind-the-scenes vibe.
  • Dugout Peeks – Candid, fun moments from the dugout, packed with personality.
Parallels across these inserts get wild, ranging from Green /99 to one-of-one Foilfractors. If rarity is your thing, Celebration packs bring plenty to chase.

Box Configuration:

  • Cards per pack: 14
  • Packs per box: 16
  • Boxes per case: 20
  • Set size: 350 cards (same as 2025 Series 1)
  • Release date: March 26, 2025
What You’ll Find Inside:

  • 16 Insert Cards (1 per pack)
  • 5 Confetti Parallels
  • A shot at autos, relics, and rare mascot hits
Who’s on the Checklist?

From Shohei Ohtani and Elly De La Cruz to Paul Skenes and James Wood, the insert and variation checklists are packed with stars—rookies, vets, and everyone in between. Mascots like Mr. Met, the Phillie Phanatic, and Wally the Green Monster round out the set with a bit of flavor.

Final Word—Without Saying It

The 2025 Celebration Mega Box isn’t just a Series 1 side product. It’s a reimagined, energized version that blends flagship structure with hobby-level creativity. Whether you’re in it for the chase, the fun inserts, or a surprise mascot auto, this box doesn’t just celebrate baseball’s return—it celebrates the thrill of collecting itself.
